Application med June 14, 1923. sperialNo. 645,424.

The present invention relates to an improvement in windows, and in general the 'object is to .provide a window sash of simple construction adapted to permit the pane of glass within the sash to be conveniently removed and replaced. As constructed, the

may bel inserted or removed very readily either prior or subsequent to the mounting of the sash within a window frame, and the sash is especially designed to facilitate the removalof the glass when the sash is within the frame, thereby permitting the glass to be handled, washed and cleaned apart from the sash and then returned to the sash all without lexposing the operator. to any risk or danger by stepping out or sitting on the ledge outside of the frame. The conception further involves the making of a sash with a slotted top rail `and a detachable top strip whereby a strong and rigid sash of rectangular form is obtained, and wherein the slotted top rail will guide a large sheet of glass and protect it from breaking when introducing it into or removing it from the sash, and wherein the detachable top strip will strengthen and permit the slotted rail to withstand lifting stresses, and also cover and guard the slot and top edge of the glass and hold the glass in place Within the sash.

In the accompanying drawing, Fig. 1 is a reduced front view of a window frame containing a pair of sliding sashes embodying our improvement. Fig. 2 is an enlarged horizontal cross section of one side rail of a sash on line 2 2 of Fig. 4. Fig. 3 is a perspective view of a portion of a sash with the glass removed and the guard strip raised apart therefrom. Fig. 4 is a vertical sect-lon and perspective view of a sash with a pane of glass secured therein.

The sash comprises a horizontal grooved hase 'strip 2, grooved upright side pieces 3 3, and a pair of .spaced cross strips 4 4 uniting the upper ends of the side pieces 3 3 rigidly together and providing a'narrow slot 5 vertically and longitudinally at the top of the sash which is open to the upper ends of the vertical grooves 7 7 in the side pieces 3 3. The slot and grooves in the sash are adapted to receive and hold a sheet of glass 6 with a snug slidingt, and the upper edge 9 ot the glass extends to and is substantially flush with the flat top surfaces 1() of the connectingstrips 4 upon which a separate detachable rail or jstrip 11 is'adapted to be seated. Rail 11 covers and closes slot 5 and is provided at its opposite ends lwith flat depending` tongues 12 of metal, and the upper' end of each side piece 3 is slotted to a substantial depthV opposite the vertical edge groove 7 therein to receive the tongue 12. A screw-threaded opening 14 within each tongue 12l registers or comes opposite an opening 15 in each side piece 3 to permit two screws 16 to be used to fasten the guard rail 11 securely but detachably in place.

Both the upper and lower sashes A andy B in a window frame C may be constructed as above described, and the advantages of the improvement are asv follows In installing a window the sashes (without the glass) may be fitted and placed within the runways and connected to weights as usual. Clean sheets of glass may then be inserted through slots 5and the guard rails or strips secured in place. Ifsash fastening areV used, these can be mounted upon the guard rails 11 in the same way as generally practiced. When the sashes Vare unlocked to permit them to be raised or lowered it is not an unusual proceeding for the operator to grip the top cross strip in liftinfr the sash, and if the sash is tight fitting or Jambed the pressure on this cross strip is considerable and very apt to break especially if it is subdivided to provide a vertical slot to permit the glass to be removed as in the present case. But by using a supplemental single heavier guard rail or strip 11 the weaker cross connecting pieces are re-enforced and such danger of breakage avoided. The sheet of glass may also be readily removed from p the sash for cleaning after the window is installed by merely detaching the guard rail, and in withdrawing the glass from the slot the double connecting strips guide and v the sashes although constructed differently do not differ much in appearance from the ordinary7 sashes in common' use, the only visible difference being the line' of union of the guard rail and the screws at each side. Viewed in its entirety the sash is simply constructed", i'i'iay be' readily substituted Jfor the sashes commonly used, permits the glass to be removed and replaced with coven ience and despatch, and no putty or other fastening means are required to s'ecnre the' glass in place other than the simple and effective meansl herein described.l Then the pane` of glass in a sash of this l-ind is broken, quick repairs and replacements can be made by anyone Withont tools other thanv a screw driver. Provision is alsojmade to permit Water to drain freely from the grooves holding the glass.v That is to say, the grooves 7" inlthelside pieces of the sash extend through the bottom strips at 18 and prevent the nater from collecting in the grooves, see Fig.

What we regard as our invention or discovery and desire to claim, 1s:

Ai Window sash, comprising a' grooved frame having slotted cross piece at its top, adapted to removably receive and seat a sheet of glass, thefnpper ends of saidy side pieces of said; frame' being slotted' additionally to a greater depth7 a detachable reenilor'cing and covering guard rail for said slotted cross piece having depending metal tongues" at its' opposite ends corresponding in thickness to said sheetof glass adapted to, extend* inte er@ Slots in the nop of the si'de pieces off the' frame `and below saidV slotted' cross piece, said metal tongues forming continuatio'ns oi sa'i'd side pieces when in place, and screws extending horizontally tli'rolngh the slotted ends of sa'id side pieces in d'e'taeliable' corn'iectionjvith said' tongues.

In testimony whereof We a'ix our signatures hereto.
